if i show identifiers column i see some zkey_file, zkey, zmi attributes, is this information convenient in this field?

Those z* Identifiers are critical to the workings of ZMI. Among other things, they provide an unambiguous audit trail from Calibre back to Zotero. Do not delete or change them. If you do, ZMI will not know what Zotero Items are already in Calibre and will add them again, or what newly created ZMI "books" are still in-process (incomplete) and should continue to be processed by ZMI. Other undesirable things can happen too.

n.b. The English word "convenient" is not used in this context. You were looking for the word "appropriate" (approprié).

#zotero_extra:identifiers but no way (#zotera_extra:#temp is working but is not very helpful)

The pushbutton called "Copy Miscellaneous ZColumns to Calibre Custom Columns [Selected Books] does just that: it copies imported Zotero metadata to Custom Columns. The ToolTips for that pushbutton explain that. The Calibre metadata column "Identifiers" is a standard column, not a Custom Column.

The only standard columns that the ZMI pushbutton called "Copy Miscellaneous ZColumns to Standard Calibre Columns [Selected Books]" copies from the appropriate ZColumns are Tags, Publisher, and Publication Date. That is because the Zotero definitions of those fields exactly match the Calibre definition of those fields. The ToolTips for that pushbutton explain that.

If you wish to copy ZColumns to arbitrary and random standard columns, you should use the Calibre Bulk Edit-Search and Replace dialog. This should be of use: https://manual.calibre-ebook.com/ .

i have custom fields for isbn, sudoc, worldcat...

If you look at this thread's Original Post, there is an attachment showing all 26 Calibre Custom Columns that are mapped from the Zotero export .csv file. You can also view them in Calibre > Preferences > Add Your Own Columns, and also see whether or not they are "hidden columns" in Calibre. You will see that #zotero_isbn is one of them. Your mission is to put your ISBN in Zotero into the Zotero ISBN field so it will automatically be mapped into #zotero_isbn. You can choose to "unhide" #zotero_isbn.

ZMI is a Calibre plug-in, not a Zotero plug-in. What Zotero metadata gets written to which export .csv file column is totally a Zotero developer decision. All you can control is putting Zotero metadata, such as your sudoc and worldcat numbers, into Zotero metadata fields such that they get mapped into the Zotero export .csv file so that they then get mapped to a Calibre #zotero_xxxxx Custom Column.

I noticed from your Zotero export .csv file that your Zotero Item Type is always "book". There is only a subset of possible Zotero metadata fields available for "book" as compared to others Item Types. For example, ZMI has a Calibre Custom Column named "#zotero_issn". ISSN is available in Zotero for periodicals, not "books". That means that you need to determine how to manipulate Zotero's Item Type to get your Zotero metadata for sudoc and worldcat into some Zotero metadata column so that it gets written by Zotero to its export .csv file within one of the 26 Zotero export .csv file columns that ZMI will import into Calibre.

PS: Zotfile seems to be incompatible with current Zotero version.

ZotFile is compatible with Zotero 5, which is the latest version. Full use of ZMI requires Zotero 5, since the SQLite database that Zotero uses had changes in some field names in Version 5.
